Hi Bob;
That works, if you grind a taper on the bars before tacking them down 
you get a bit more mileage out of it.
Once these are roughed out by hand  ( that's pretty quick) and annealed 
or hot, they can be stuck between a set of matching cones  and forced 
smooth.
I still have a wire basket of extras from 25 years ago rusting in the 
yard...been using them one by one for a long time.....PF
